Boucher CO, Zwemer TJ. All animals have two mandibles, not one; removing one entire mandible is a total mandibulectomy not a hemimandibulectomy, The part that carries the teeth; often incorrectly referred to as horizontal ramus, The part that carries the premolars and molars; premolar-molar part would probably have been more accurate, Often incorrectly referred to as alveolar crest, Contains a neurovascular bundle; often incorrectly referred to as the medullary cavity of the mandible, Rostral, middle or caudal mental foramina in the dog and cat, The part that carries the 3 processes; often incorrectly referred to as the vertical ramus, Process for the attachment of the temporal muscle, Consisting of mandibular head and mandibular neck; often incorrectly referred to as condyloid process, The notch on the caudal aspect, between the coronoid and condylar processes; not to be confused with the facial vascular notch. 1st ed.

It is intended to control local irritational factors. The modified Triadan system is presently considered to be the tooth numbering system of choice in veterinary dentistry; gaps are left in the numbering sequence where there are missing teeth (for example, the first premolar encountered in the feline left maxilla is numbered 206, not 205. The registration of an AVDC training program of an individual who is not in compliance with the policy stated above may be terminated by AVDC, in which case the individual will not be permitted to complete the AVDC credentials and/or the examination procedures, and, when appropriate, the circumstances may be reported by AVDC to the individual’s State Board of Veterinary Medical Examiners.

Following the acceptance of the new system for human dental nomenclature, Professor DrMedDent H. Triadan, a dentist at the University of Bern, Switzerland, introduced a similar system for animals. Tooth resorption is classified based on the severity of the resorption (Stages 1-5) and on the location of the resorption (Types 1-3). Interceptive procedures are typically undertaken in the growing patient. CAL: Clinical attach-ment loss. The latter term, however, can be confused with an unerupted deciduous tooth. Author J B Suzuki 1 Affiliation 1 Department of Periodontics, University of Maryland, Baltimore. In 1989, a classification system was proposed that included five types of periodontitis: adult periodontitis, early onset periodontitis, periodontitis associated with systemic disease, necrotizing ulcerative periodontitis, and refractory periodontitis.

2. A vein used to take place of a removed segment of artery/vein or arterial/venous defect. A new periodontal disease classification system was recommended by the 1999 International Workshop for a Classification of Periodontal Disease and Conditions2 (Table 2) and has been accepted by the AAP. In its early stage, called gingivitis, the gums can become swollen and red, and they may bleed. Berlin: Verlag Paul Parey, 1973;75-99.

Comment(s): The term “facial” specifically refers to the surfaces of the rostral teeth visible from the front. Periodontal diseases are mainly the result of infections and inflammation of the gums and bone that surround and support the teeth. Furcation 2 involvement exists when a periodontal probe extends greater than half way under the crown of a multirooted tooth with attachment loss but not through and through. Actions. The mandibular canine tooth is inclined labially and bisects the interproximal (interdental) space between the opposing maxillary third incisor tooth and canine tooth.

It was determined that the previous AAP 1999 classification did not cater for the needs of patients with peri-implant diseases and conditions. A type of partial-thickness graft in which multiple small incisions have been made to increase stretching and flexibility of the graft. It is normally referred to as IWCP 1999 classification but also as the AAP 1999 classification. The AAP advises that periodontal disease should always be treated in the “least invasive and most cost-effective manner.” 7 Dental hygienists understand that scaling removes biofilm and calculus from the teeth and that root planing involves a degree of smoothing the root surface to prevent periodontal bacteria from sticking to it. Physical trauma sustained from a projectile that was launched through space, most commonly by a weapon such as a gun or a bow. The part of the palate supported by bone. In addition to reports that were prepared prior to the World Workshop, there were 4 working groups at the meeting and each issued a consensus report at the conclusion of the meeting. 3rd ed.

Class 2: Patients with a current dental examination, who require non-urgent dental treatment or reevaluation for oral conditions, which are unlikely to result in dental emergencies within 12 months. This is then further categorised by staging and grading the periodontitis. Example: A fracture of the crown1 that exposes the pulp.
